1、第一类：one 一two 二three 三four 四five 五six 六seven 七eight 八nine 九ten 十eleven 十一twelve 十二这一类共计十二个单词，在结构上与其他的基数词相比较是特殊的，就象不规则的动词一样，要求逐个的硬背下来，这对学好其他的基数词和序数词都是及其重要的。
2、第二类：thirteen 十三fourteen 十四fifteen 十五sixteen 十六seventeen 十七eighteen 十八nineteen 十九这一类基数词共有七个。
它们在结构上有两个特点：一是在发音方面都有两个重音；二是在拼法上都有后缀－teen。
除了thirteen和fifteen之外，都是纯粹地在另一个基数词的后面加上后缀－teen。
但要注意eighteen的拼法，eight本身有t字母，因此只加－een。
3、第三类：twenty 二十thirty 三十forty 四十fifty 五十sixty 六十seventy 七十eighty 八十ninety 九十这类基数词共有八个。
